Lavie se souvient du jour où son père et celui de Claus partirent pour affronter le "grand courant" et n'en revinrent jamais.

While Lavie recovers from her injuries on the crashed Silvana, she dreams of her childhood with Claus, whose family moved to Norkia and became neighbors with Lavie's. Their fathers, Hamilcar Valca and Georges Head, immediately became best friends and teamed up as a vanship pilot and navigator. Claus's mother, Justina, took care of Lavie as if she was her own daughter. Valca and Head taught their children to fly a vanship and assigned them mock courier missions. Lavie recalls her father's two friends, a male vanship pilot and a female navigator, but cannot remember their names. One day, Valca and Head received an assignment to cross the Grand Stream to deliver a peace proposal to Disith and left with their two friends. However, Valca and Head lost their lives in the attempt, and Justina died not long after. In a separate dream, Alex Row sees the two vanships in the Grand Stream. After they were orphaned, Claus and Lavie began training to fly a vanship. They were eventually forced to sell their house to save the vanship and began training for courier missions. When Lavie finally awakens, she finds herself crying from the memories. Dio and Alister finally locate Claus and Tatiana near the field of Disith migration capsules. Claus is reunited with Lavie and informs her that their hometown of Norkia has fallen to Disith.

Lavie, svenuta durante la caduta della Silvana, in sogno ha un'analessi riguardante la sua infanzia e quella di Claus, cresciuti dai genitori a Norkia; i padri dei due giovani erano amici e abilissimi piloti di vanship, con Hamilcar Valca come pilota ufficiale e Georges Head in qualità di navigatore, ed erano in stretta relazione con una coppia di fidanzati anch'essi piloti di vanship, dei quali il ragazzo regalò a Lavie la capra peluche.

クラウスの父親とラヴィの父親は、国中に名を馳せたヴァンシップ乗りだった。10年前、彼らのチームは、ある重大な任務を持って、グランドストリーム超えに挑んだ。
